FRESNO, Calif. — A federal grand jury returned an indictment Thursday against Raquel Mosqueda, 36, of Porterville, California, and Jimmie L. Carter, 44, charging them with conspiring to violate the constitutional rights of another inmate at California State Prison-Corcoran, United States Attorney Phillip A. Talbert announced. 

Mosqueda was a Correctional Officer with the California Department of Corrections and Rehabilitation, and Carter was an inmate.  According to court documents, on or around April 20, 2022, Mosqueda, while serving as a correctional officer at California State Prison-Corcoran, agreed with Carter to permit Carter to “get rid of” the victim.  Mosqueda facilitated an assault of the victim by permitting Carter and other inmates to enter the victim’s cell and assault him.  The assault caused bodily injury to the victim.

Mosqueda is additionally charged with depriving the victim of his constitutional right to be free from cruel and unusual punishment, which includes the right to be reasonably protected from the threat of violence by fellow inmates.

This case was the product of an investigation by the Federal Bureau of Investigation and California Department of Corrections and Rehabilitation’s Office of Internal Affairs.  Assistant United States Attorney Karen A. Escobar and Trial Attorney Laura-Kate Bernstein of the Civil Rights Division of the U.S. Department of Justice are prosecuting the case.

If convicted, Mosqueda and Carter face a maximum statutory penalty of 10 years in prison and a $250,000 fine for the conspiracy charge.  Mosqueda faces an additional 10 years in prison and a $250,000 fine for the charge of deprivation of constitutional rights. Any sentence, however, would be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables. The charges are only allegations; the defendant is presumed innocent until and unless proven guilty beyond a reasonable doubt.

This case was the product of an investigation by the Federal Bureau of Investigations. Assistant United States Attorney Jessica Delaney is prosecuting the case.

If convicted, Chartraw faces a maximum statutory penalty of 20 years in prison and a $250,000 fine. Any sentence, however, would be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables. The charges are only allegations; the defendant is presumed innocent until and unless proven guilty beyond a reasonable doubt.

Two Aryan Brotherhood Prison Gang Members Sentenced to Two Consecutive Life Terms in Prison for RICO Conspiracy and Murder in Aid of Racketeering

Source: US FBI

SACRAMENTO, Calif. — Ronald Yandell, 62, of Pinole, and William Sylvester, 56, of Norco, were each sentenced today by U.S. District Judge Kimberly J. Mueller to two consecutive life terms in prison for murder in aid of racketeering and various other RICO-related crimes, United States Attorney Phillip A. Talbert announced.

According to court documents, between 2011 and 2016, Aryan Brotherhood members and associates engaged in racketeering activity, committing multiple acts involving murder, conspiracies to murder, and drug trafficking crimes. The trial evidence showed that Aryan Brotherhood members oversaw a significant heroin and methamphetamine trafficking operation from their California prison cells using smuggled cellphones to direct drug trafficking activities, order murders, and oversee other criminal activities inside and outside of the prisons.

Yandell’s murder in aid of racketeering

According to evidence presented at trial, on August 15, 2015, two inmates carried out a brutal murder of another inmate at CSP-Sacramento on Yandell’s order.  Before the murder, Yandell offered the two inmates membership in the Aryan Brotherhood if they were able to execute the killing.  About a year after the murder, DEA intercepted calls made by Yandell over a contraband cellphone in which he bragged about directing the murder and sponsoring the killers for membership in the gang.  Yandell also directed that money earned from Aryan Brotherhood criminal activities be directed to support the two murderers.

Sylvester’s murder in aid of racketeering

According to evidence presented at trial, on October 7, 2001, Sylvester murdered another inmate at CSP-Sacramento to earn his membership in the Aryan Brotherhood.  In particular, Sylvester murdered the other inmate because the victim was a member of a gang that refused to recognize the Aryan Brotherhood’s authority and, as a result, members of the victim’s gang were marked for death. 

To carry out the murder, Sylvester and another inmate used substantial planning and premeditation to carry out the attack within an extremely-restrictive prison environment. They used inmate-manufactured weapons and surprised the victim with multiple lethal stab wounds to the victim’s body. Sylvester earned membership in the gang for carrying out the killing.

In April 2024, following a nine-week trial before, a federal jury found Yandell, Sylvester, and co-defendant Danny Troxell, 71, guilty of RICO conspiracy, conspiracy to murder, murder in aid of racketeering, and multiple counts of drug trafficking.  Troxell will be sentenced on February 18, 2025.

Charges remain pending against one defendant, Kevin MacNamara, 44, of La Palma.

The charges are only allegations; the defendants are presumed innocent until and unless proven guilty beyond a reasonable doubt.

This case is the product of an investigation by the Drug Enforcement Administration with assistance from the California Department of Corrections and Rehabilitation, the Vallejo Police Department, the U.S. Marshals Service, the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Federal Bureau of Investigation, the El Dorado County District Attorney’s Office, and the Nevada County Sheriff’s Office. Assistant U.S. Attorneys Jason Hitt, Ross Pearson, and David Spencer are prosecuting the case.

The case was investigated under the Organized Crime Drug Enforcement Task Forces (OCDETF).

SACRAMENTO, Calif. — Randy Anger, 57, of Carnelian Bay, pleaded guilty today to distribution and receipt of child pornography, United States Attorney Phillip A. Talbert announced. 

According to court documents, in May 2021, Anger distributed and received child sexual abuse material on the Kik Messenger app while communicating with Brent Hooton.  Hooton was separately charged and convicted in the Eastern District of California with production and distribution of child pornography and was sentenced to 27 years in prison.  In November 2021, Anger also received several images of child sexual abuse material on the Wickr app.

This case was the product of an investigation by the Federal Bureau of Investigation, with assistance by Homeland Security Investigations and the Placer County Sheriff’s Office. Assistant United States Attorney Denise N. Yasinow is prosecuting the case.

Anger is scheduled to be sentenced on March 31, 2025, by U.S. District Judge Dale A. Drozd.  On both the distribution and receipt counts, he faces a mandatory minimum sentence of 5 years in prison and a maximum statutory penalty of 20 years in prison per count. The actual sentence, however, will be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables.

This case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 by the Department of Justice to combat the growing epidemic of child sexual exploitation and abuse. Led by the United States Attorneys’ Offices and the Criminal Division’s Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state, and local resources to locate, apprehend, and prosecute those who sexually exploit children, and to identify and rescue victims.

Kern County Woman Sentenced to Five Years for $825,000 Credit Card Fraud Scheme Where She Used Identities Stolen From Health Care Providers

Source: US FBI

FRESNO, Calif. — Karina Arceo, 34, of Wasco, was sentenced to 60 months in prison and 3 years of supervised release for conspiring to commit bank fraud and committing aggravated identity theft in a long-running credit card fraud scheme, U.S. Attorney Phillip A. Talbert announced today.

“The defendant used patient healthcare files to commit fraud and identity theft instead of treating those files with the care and sensitivity they deserve,” said U.S. Attorney Talbert. “Let this case serve as a warning those who consider abusing such access to patient files: my office will work tirelessly with the FBI and our law enforcement partners to investigate and prosecute fraud and identity theft crimes committed with sensitive patient information.”

“Arceo violated her employer’s trust by abusing her access to personally identifiable information, fueling an elaborate, greed-driven scheme that she and her partner enjoyed until they were taken into custody,” said FBI Sacramento Special Agent in Charge Sid Patel. “This case should serve as a reminder to all to freeze and routinely check your credit to ensure accounts are not opened without your knowledge. It is also a reminder to would-be criminals that the FBI will identify and pursue anyone who abuses a position of trust to exploit others for personal gain.”

According to court records, from February 2016 through August 2022, Arceo and her partner and co-defendant, Miguel Leyva, stole the personally identifiable information (PII) for more than 125 victims. They stole much of the PII from patient files at health care providers in Kern County where Arceo worked.

As part of their fraud scheme, Arceo and Leyva used the stolen PII to open thousands of fraudulent credit cards in the victims’ identities and made hundreds of thousands of dollars in fraudulent purchases on the credit cards in Fresno County, Kern County, the Bay Area, and elsewhere. The fraudulent purchases included home appliances, furniture, wall art, automobile accessories, designer clothing and shoes, luxury camping equipment, tickets to concerts and sporting events, and travel, among other items. Indeed, they used fraudulent purchases to remodel their home kitchen and their child’s room.

Arceo and Leyva also resold many of the items that they fraudulently purchased for cash and reaped a windfall because they did not actually pay for the items. They also used checks that had been stolen from companies in Kern County to access the companies’ bank accounts and make fraudulent payments towards the credit cards so as to keep their scheme going. Altogether, their scheme caused a total actual loss of more than $825,000.

Selfie of defendants celebrating after fraudulent purchase at Bed, Bath, & Beyond

Arceo’s sentence was enhanced because text messages that she exchanged with Leyva showed that she was the leader of the scheme. Arceo would pull the stolen PII used to open the fraudulent credit cards from her cloud account and send it to Leyva. The text messages also showed that Arceo would coach Leyva on how to make the fraudulent purchases. For example, she would tell him which cashiers to target at the stores and what to say if the cashiers started asking questions. Finally, the text messages showed that Arceo used lyrics from a popular hip-hop song at the time to describe herself as being “the boss” of the scheme who “makes money move” and to Leyva as just being a “worker.”

Leyva was previously sentenced to 65 months in prison.

At the sentencing hearing, Arceo submitted a letter to the court that Leyva wrote from prison where he tried to minimize her role in the scheme and identified himself as being the leader. That argument was rejected by the court.

This case is the product of an investigation by the Federal Bureau of Investigation. Assistant U.S. Attorneys Joseph D. Barton and Arelis M. Clemente are prosecuting the case.

Bitwise Founders Sentenced to 11 Years and Nine Years in Prison for $115 Million Fraud

Source: US FBI

FRESNO, Calif. —Jake Soberal, 38, and Irma Olguin, Jr., 44, the founders and leaders of the failed Fresno-based start-up company, Bitwise Industries (“Bitwise”), were sentenced to 11 years and 9 years in prison, respectively, for defrauding people out of approximately $115,000,000, United States Attorney Phillip A. Talbert announced today.

“Defendants likened themselves to gods and joked about deceiving their well-intentioned investors while committing a massive fraud,” said U.S. Attorney Talbert.  “They lied repeatedly to pull in over $100 million to a dying business venture that they knew never had any meaningful revenue.  To make themselves rich and keep up the façade, they used fabricated bank statements, false financial information, forged documents, and fake loan collateral.  These sentences serve as a reminder of the hazards of such financial crimes, and my office will continue to work with the FBI, IRS Criminal Investigation, and our law enforcement partners to vigorously investigate and prosecute those who commit them.”

“The willful and egregious fraud carried out by Irma Olguin Jr. and Jake Soberal will have long lasting impacts on not only those who invested in the well-orchestrated scam of Bitwise, but also the nearly 1,000 employees and contractors who abruptly lost their jobs when the Bitwise swindlers ran out of money,” said IRS Criminal Investigation (IRS-CI) Oakland Field Office Assistant Special Agent in Charge Kulbir Mand. “White-collar crimes are damaging to victims, families, and communities alike. IRS-CI and its law enforcement partners are experts at investigating financial crimes and building cases that lead to justice. Today’s sentencing should serve notice that the consequence for committing white-collar crime is severe.”

“This case demonstrates how disastrous the impact can be when a company’s executives fail to conduct themselves ethically and lawfully.  Bitwise Industries co-CEOs Jake Soberal and Irma Olguin, Jr. repeatedly lied to investors and lenders to keep their massive Ponzi scheme afloat, despite knowing that the business model would never generate positive revenue. The $115 million loss is significant, but the damage to the professional reputations of innocent parties and the loss of more than 900 jobs and associated benefits employees depended on will have a lasting, negative impact on the economy and individual lives,” said FBI Sacramento Special Agent in Charge Sid Patel. “The FBI remains steadfast, safeguarding our economy by working with all partner agencies to ensure that those who exploit positions of trust to commit large-scale corporate frauds are held accountable for their criminal activity.”

According to court records, Bitwise was, and still is, the biggest startup company to come from California’s Central Valley.  The company’s objective was to use technology to create jobs for underserved groups of people, revitalize blighted urban areas, and show that such a project could be profitable.

Olguin, Jr. and Soberal received national media attention by appearing in publications like Forbes Magazine and giving Ted Talks where they portrayed Bitwise as being a success.  They also made a substantial annual salary.  By early 2022, however, the company was not generating any revenue and was running low on funds.  Thereafter, Olguin, Jr. and Soberal fabricated financial information for its board and for investor materials and doctored audit reports to make it appear as though Bitwise was generating revenues and turning a profit.  They also altered bank statements and forged bank representatives’ signatures on bank correspondence to inflate the company’s cash balances.  They did so to convince people that Bitwise was excelling when the company was actually failing.

The following are illustrative examples of Olguin, Jr. and Soberal’s fraud:

  • In a February 2022 presentation and July 2022 prospectus that were circulated to investors, Olguin, Jr. and Soberal represented that Bitwise’s cash balance was over $44,000,000 as of the end of 2021.  They also represented that the company’s revenue was more than $58,000,000.  In reality, the company’s cash balance was less than $12,000,000 at that time and its revenue was non-existent. 
  • In June and July 2022, Olguin, Jr. and Soberal falsely represented to a California-based investment firm that Bitwise had secured a $150,000,000 investment from another, London-based investment firm.  This was done to convince the California-based investment firm to purchase several buildings that Bitwise owned.  Several months later, Soberal falsely represented to another lender that Bitwise still owned those buildings to to provide collateral for another loan from another lender of millions of dollars. 
  • In a March 2023 presentation circulated to investors, Olguin, Jr. and Soberal represented that Bitwise’s cash balance was over $77,000,000 as of the end of 2022.  They also represented that the company’s revenue was more than $143,000,000.  In reality, the company’s cash balance was less than $5,000,000 at that time and its revenue nominal. 
  • Also in March 2023, Olguin, Jr. and Soberal provided an investor with an altered version of an audit of Bitwise that was previously conducted by an international audit firm.  They altered the audit to make it appear as though Bitwise’s revenue was 300 percent higher than the true number. 
  • Also in March 2023, Soberal represented to a long-time Bitwise employee that the company had sufficient resources on-hand to induce the employee to make a significant loan to the company.

This pattern continued until the end of May 2023 when Bitwise ran out of money and the company collapsed.

Olguin, Jr. was a computer engineer who had previously run another technology company, and Soberal was an attorney who had previously practiced at a law firm doing intellectual property work.  Moreover, the defendants hired unqualified family members and friends, which allowed them to compartmentalize information and work in secret to spin the false statements needed to conceal and continue with their fraud.  For these reasons, Olguin, Jr. and Soberal received special sentencing enhancements. 

This case is the product of an investigation by the FBI and IRS Criminal Investigation.  Assistant United States Attorneys Joseph Barton and Henry Z. Carbajal III prosecuted the case.

Southern California Political Operative Arrested on Federal Complaint Alleging He Acted as Illegal Agent of People’s Republic of China

Source: US FBI

LOS ANGELES – FBI agents this morning arrested a Chino Hills man on federal charges that allege he acted as an illegal agent of the People’s Republic of China (PRC), including while serving as the campaign manager for a political candidate who was elected in 2022 to the city council of a Southern California city.

Yaoning “Mike” Sun, 64, was arrested without incident and is expected to make his initial appearance this afternoon in United States District Court in downtown Los Angeles.

criminal complaint filed Tuesday and unsealed this morning charges Sun with acting as an illegal agent of a foreign power. Sun is also charged with conspiring with another man, Chen Jun, who was sentenced to federal prison last month for acting as an illegal agent of the PRC government and plotting to target U.S.-based practitioners of Falun Gong, a spiritual practice banned in China.

According to the complaint, Sun served as the campaign manager and close personal confidante for a Southern California politician (described in the affidavit as “Individual 1”) who was running for local elected office in 2022. During the campaign, Sun allegedly communicated with Chen regarding his efforts to get Individual 1 elected. Chen discussed with Chinese government officials how the PRC could “influence” local politicians in the United States, particularly on the issue of Taiwan, according to the complaint. In November 2022, shortly after Individual 1 was elected to office, Chen instructed Sun to prepare a report on the election that was sent to Chinese government officials, who responded positively and expressed thanks, according to the complaint affidavit. Chen also sent a message to Individual 1 stating that Individual 1 was “doing a good job, I hope you can continue the good work, make Chinese people proud,” the affidavit states.

“The conduct alleged in this complaint is deeply concerning – the defendant is charged with acting on behalf of the People’s Republic of China to influence our political system,” said United States Attorney Martin Estrada. “We cannot permit hostile foreign powers to meddle in the governance of our country. My office and our law enforcement partners will continue to prioritize the security of our nation and the preservation of the liberties that make this country the envy of the world.”

“This case highlights the breadth of the PRC’s relentless intelligence and malign influence activities targeting the United States,” said Akil Davis, the Assistant Director in Charge of the FBI’s Los Angeles Field Office. “The FBI will continue to use all the tools at its disposal to identify PRC intelligence operations, disrupt PRC information laundering networks, and bring to justice those who seek to engage in criminal conspiracies to undermine the integrity of our elected officials.”

About a month after Individual 1’s election, Chen arranged a lunch at a Rowland Heights restaurant with Sun and others, a gathering that Chen described to a PRC official as a “core member lunch,” the affidavit alleges. Chen subsequently described the lunch as “successful” as participants agreed to establish a “US-China Friendship Promotional Association.” While Individual 1 did not attend the meeting, Chen described Individual 1 as being part of the association and Sun serving as vice president. “This is the basic team dedicated for us,” Chen wrote to the Chinese government official.

Chen instructed Sun in early 2023 to write up another report for Chinese officials describing “you and me cultivating and assisting [Individual 1’s] success,” according to the affidavit. In a February 2023 draft of Sun’s report, Sun described his personal background, his history of working against “Chinese secessionist forces,” and boasted that, “most proudly of all, during the 2022 U.S. midterm elections, I orchestrated and organized my team to win the election for city council member candidate [Individual 1].” In subsequent communications outlined in the affidavit, Chen instructed Sun to include a section on Individual 1, who was to be described as a “New Political Star” with connections to other prominent politicians. The affidavit also states that Chen and Sun discussed their “past struggle fighting Taiwanese independence forces . . . over the years and fighting ‘FLG’ [Falun Gong] influences” in a California city.

In February 2023, Sun and Chen drafted a second report to PRC officials that requested an $80,000 budget to fund additional pro-PRC activities and to combat “anti-China forces” in the United States.   

After Chen and Sun discussed a planned trip to the PRC to meet with “leadership,” and after Chen directed Sun to schedule a meeting with the Chinese consul general in Los Angeles, Sun and Individual 1 traveled to China in late August 2023.

A criminal complaint is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.

The charge of acting as an illegal agent of a foreign government carries a statutory maximum sentence of 10 years in federal prison. The charge of conspiracy to commit an offense against the United States carries a maximum statutory sentence of five years.

This FBI is conducting the ongoing investigation in this matter.

Assistant United States Attorney David Ryan, Chief of the National Security Division, and Assistant United States Attorney Amanda Elbogen of the Terrorism and Export Crimes Section are prosecuting this case, with assistance from Trial Attorney Garrett Coyle of the Counterintelligence and Export Control Section in the Department of Justice’s National Security Division.

Rancho Cucamonga Man Sentenced to More Than Three Years in Prison for Operating ‘Birth Tourism’ Scheme for Affluent Chinese Clients

Source: US FBI

LOS ANGELES – A San Bernardino County man was sentenced today to 41 months in federal prison for operating a “birth tourism” scheme that charged Chinese clients tens of thousands of dollars to help them give birth in the United States to obtain birthright U.S. citizenship for their children.

Michael Wei Yueh Liu (刘维岳), 59, of Rancho Cucamonga, was sentenced by United States District Judge R. Gary Klausner.

At the conclusion of a four-day trial, a jury on September 13 found Liu and Jing Dong, (董晶), 47, of Rancho Cucamonga, guilty of one count of conspiracy and 10 counts of international money laundering. Dong is expected to be sentenced in the coming weeks.

From at least January 2012 to March 2015, Liu and Dong ran a maternity house in Rancho Cucamonga. Liu and Dong rented apartments in Southern California to provide short-term housing and provided other services to pregnant women from China who traveled to the United States to give birth so their children would acquire U.S. citizenship. Typically, within one or two months after giving birth, the women returned to China.

Among the services Liu and Dong provided were assistance on how to obtain visas to enter the United States, customs entry guidance, housing, and transportation in the United States, as well as assistance applying for U.S. legal documents for the children of their customers.

Liu and Dong advised their customers on how to hide their pregnancies from the immigration authorities. Liu and Dong also knew – or deliberately avoided learning – that their customers lied on their visa applications submitted to immigration authorities to enter the U.S.

Generally, their customers’ visa applications falsely stated that the purpose of the trip to the United States was for tourism, when it was to give birth, and the length of the stay was days or weeks, when it was in fact months. The visas also misstated the location where the customers intended to stay, which was defendants’ maternity hotel.

Liu and Dong or their agents also advised their customers to fly to ports of entry with perceived less customs scrutiny, such as Hawaii, before flying to Los Angeles, to wear loose fitting clothing, to favor certain lines at customs that they perceived to be less strict, and on how to answer the customs officials’ questions.

Liu and Dong received money from overseas and used that money to promote their scheme.

Homeland Security Investigations, IRS Criminal Investigation, and the FBI investigated this matter. The Irvine Police Department and the San Bernardino County Sheriff’s Department provided substantial assistance.

Assistant United States Attorneys Gregory W. Staples and Kevin Y. Fu of the Orange County Office prosecuted this case.

Santa Paula Doctor Sentenced to Two Years in Federal Prison for Role in Hospice Fraud That Bilked Medicare Out of $3.2 Million

Source: US FBI

LOS ANGELES – A Ventura County physician who worked for two Pasadena hospices was sentenced today to 24 months in federal prison for defrauding Medicare out of more than $3 million through claims for medically unnecessary hospice services.

Dr. Victor Contreras, 69, of Santa Paula, was sentenced today by United States District Judge André Birotte Jr., who also ordered him to pay $3,289,889 in restitution. 

Contreras pleaded guilty on July 24 to one count of health care fraud.

From July 2016 to February 2019, Contreras and co-defendant Juanita Antenor, 62, formerly of Pasadena, schemed to defraud Medicare by submitting nearly $4 million in false and fraudulent claims for hospice services submitted by two hospice companies: Arcadia Hospice Provider Inc., and Saint Mariam Hospice Inc. Antenor controlled both companies.

Medicare only covers hospice services for patients who are terminally ill, meaning that they have a life expectancy of six months or less if their illness ran its normal course.

Contreras falsely stated on claims forms that patients had terminal illnesses to make them eligible for hospice services covered by Medicare, typically adopting diagnoses provided to him by hospice employees whether or not they were true. Contreras did so even though he was not the patients’ primary care physician and had not spoken to those primary care physicians about the patients’ conditions. Medicare paid on the claims supported by Contreras’ false evaluations and certifications and recertifications of patients.

In total, approximately $3,917,946 in fraudulently claims were submitted to Medicare, of which a total of approximately $3,289,889 was paid.

According to Medical Board of California records, Contreras is a licensed physician in California, but has been on probation with the Board since 2015 and is subject to limitations on his practice. 

Antenor remains at large. Co-defendant Callie Black, 66, of Lancaster, who allegedly recruited patients for the hospice companies in exchange for illegal kickbacks, has pleaded not guilty and is scheduled to go to trial on March 4, 2025.

An indictment contains allegations that a defendant has committed a crime. Every defendant is presumed to be innocent until and unless proven guilty in court.

The United States Department of Health and Human Services Office of Inspector General, the FBI, and the California Department of Justice investigated this matter.

Assistant United States Attorneys Kristen A. Williams of the Major Frauds Section and Aylin Kuzucan of the General Crimes Section are prosecuting this case.
